💡 Accuracy - Efficiency - Customization. 💡
That’s the Environics difference.
Environics is a global leader in computerized gas flow systems, delivering precision-engineered solutions for gas mixing, dilution, and calibration. For over four decades, we've empowered R&D labs, environmental agencies, and industrial innovators with systems that offer consistent, repeatable accuracy and on-demand customization.
Our proprietary technology eliminates the frustrations of pre-mixed cylinders - no more unpredictable gas concentrations, rising storage costs, or unreliable equipment. Instead, we provide flexible systems with intuitive controls and advanced feedback loops, tailored to your exact application requirements.
Why Customers Trust Environics:
- Unmatched Accuracy: Our systems deliver consistent results that protect the integrity of your critical processes.
- Operational Efficiency: Generate exactly what you need - when you need it - with real-time gas blending.
- Custom Engineering: From ultra high-purity configurations to humidification and permeation, our solutions are built for your environment.
We offer complete support throughout the lifecycle of your system - from initial consultation and custom design through validation, training, and ongoing service.
At Environics, we make precision simple so you can stay focused on what matters most.

Our five-year projections show continued growth through the introduction of new products and product innovations. All service is handled factory direct. Sales are handled direct and by distributors worldwide.
At Environics, our team is dedicated to customer service before, during and after your system is built. We stand by our systems and believe in building long-term relationships with our customers.
Our Technology
Our gas mixing technology is based on very precise control of thermal mass flow controllers (MFCs). Normally, thermal MFCs offer an accuracy +/- 1% of full-scale flow. However, when combined with Environics computerization and calibration, this accuracy specification is improved to +/- 1% of setpoint. The Full-scale error vs. Setpoint error document shows the 10x improvement in accuracy of a thermal MFC when using Environics controlling technology. Our calibrators and dilution systems exceed the accuracy required by the EPA for Ambient Calibrators (ref: Method 205, 40CFR51, 40CFR60, 40CFR75). For more technical information, see our Technical Documents section, which contains current articles and CFR's pertinent to our technologies.
We encourage you to challenge us with your most difficult requirements. We specialize in custom systems. We have thousands of systems in the field and have developed an extensive library of applications and solutions to meet our customers' needs. The application of our technology has enabled us to become the world leader in user-friendly computerized gas flow instrumentation.
